Abstract

PROBLEM TO BE SOLVED: To eliminate the thrust of a piercing pin in a hard place so as to be easy to walk by providing a piercing pin set so as to be protruded to the lower surface of a shoes bottom by the working force of a spring and recessed when an external force larger than the working force is recessed on a cylindrical body fixed to the shoes bottom by insert. SOLUTION: A topped cylindrical main body 3 with a collar 2 to be fixed to a shoes bottom 1 by insert is constituted, a bottomed cylindrical auxiliary body 4 is fitted thereto, and the lower edge of the cylindrical main body 3 is turned down to the inside to integrate the cylindrical main body 3 to the cylindrical auxiliary body 4. A piercing pin 8 having a thickness fitted to a through-hole 5 in the slidable state without play is provided in the center of the lower end surface of an inner cylinder member 7, and a coil spring 9 is inserted into the inner cylinder member 7 to press the upper end of the coil spring 9 onto the top wall of the cylindrical main body 3, and also make the upper end 10 of the inner cylinder member 7 contactable with the top wall. When the piercing pin 8 is pressed by an external force stronger than the working force of the coil spring 9, the whole body excluding a tip part 12 of the piercing pin 8 is recessed into the through-hole 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spike for shoes attached to the bottom of shoes such as golf shoes.

[0002]

2. Description of the Related Art A conventionally known spike of a golf shoe has a configuration in which a piercing pin does not protrude and protrudes, so that it is pushed up in a hard place when walking, which is inconvenient for walking.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a novel shoe spike which has been devised to solve the above-mentioned disadvantages and has been devised.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, a shoe spike according to the present invention comprises a tubular body fixed to a shoe sole by an insert, and the tubular body is acted on by a spring force. It is provided with a piercing pin which is protruded from the lower surface of the shoe sole and is immersed when subjected to an external force larger than the acting force,

[0005] A stopper portion is provided which comes into contact with the piercing pin when the piercing pin is immersed and maintains a semi-submerged state in which only the tip of the piercing pin protrudes.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the figures, a cylindrical main body 3 with a flange 2 is fixed to a shoe sole 1 by insert, and a cylindrical auxiliary body 4 with a bottom is fitted into the cylindrical main body 3. After being worn, the lower end edge of the cylindrical main body 3 is folded inward to integrate the cylindrical main body 3 and the cylindrical auxiliary body 4, and a through-hole 5 communicating with the bottom wall of the cylindrical auxiliary body 4 inside and outside. In addition, the inner cylindrical member 7 that can move up and down is inserted into the cylindrical auxiliary body 4 along the inner peripheral surface of the cylindrical auxiliary body 4, and the outer periphery of the lower end surface of the inner cylindrical member 7 is It is locked to the upper surface of the cut edge of the through hole 5 so that it cannot be pulled out, and fits in the center of the lower end surface of the inner cylindrical member 7 in the through hole 5 slidably without play. A piercing pin 8 having a thickness is provided, and a coil spring 9 is further inserted into the inner cylinder member 7 so that the upper end of the coil spring 9 is pressed against the top wall of the cylindrical main body 3 and the inner cylinder member 7 is attached to the top wall. The end 10 can be abutted, and when the lower end surface of the inner cylindrical member 7 abuts on the upper surface of the cut edge of the through hole 5, the whole except the base end 11 of the piercing pin 8 is out of the through hole 5. When the piercing pin 8 is pushed out by the action force of the coil spring 9 and the piercing pin 8 is pushed in by an external force stronger than the action force of the coil spring 9, when the upper end surface of the inner cylindrical member 7 comes into contact with the top wall of the tubular main body 3, the piercing pin 8 The whole except the tip 12 is immersed in the inside of the through hole 5 (specifically, the piercing pin 8 is immersed in a state in which the tip of the piercing pin 8 projects outward by about 1 to 2 mm). is there. Reference numeral 13 in the drawing denotes a hole for preventing the bottom constituent resin from flowing and rotating the whole when the insert is fixed. In the present invention, an elastic material such as rubber may be used in place of the coil spring 9 as an elastic machine.

[0007]

According to the spike for shoes according to the present invention, when walking while wearing golf shoes to which the spike is attached, the ammunition shrinks in a hard place, and the piercing pin is immersed to eliminate thrust. The piercing pin can pierce the ground by the force of the machine to enhance the grip, and the hollow formed by the insertion of the ammunition can possibly achieve a lighter weight. When the piercing pin is immersed in the shoe spike, the tip is slightly protruded so that the grip is not completely lost, and it is difficult for the spike to slip even in a hard place. When asobi is not formed between the piercing pin and the immersion hole of the pin as in the embodiment, the through-hole is always closed by the piercing pin, so that soil or dirt may be contained in the immersion hole. Good condition without sand A.
